DYEING-MACHINE.

To all whom it may cancer Be it known that we, ROBERT P. SMITH andGEORGE E. DRUM, citizens of the United States, and JAMES H. SKITT,subject of the King of England, residing at Philadelphia, in the countyof Philadelphia and State of Pennsylvania, have invented certain new anduseful Improvements in Dyeing-Machines, of which the following is aspecification.

The object of this invention is to provide a dyeing machine for dyeinghosiery and other knit goods in a manner that will cause them to bethoroughly impregnated with the dye liquor, and at the same time preventthem from being agitated to an extent to cause them to be roughened ortangled.

Broadly, the invention consists of an outer tank to contain the dyeliquor, and an inner cage or receptacle for the goods to be dyed, saidinner cage having perforated top and bottom and being reciprocated'vertically within the tank to plunge the'goods downwardly into the dyeliquor for impregnation, and upwardly to create a vacuum or suctionwithin the lower portion of the tank to suck the dye liquor downwardthrough the goods and into the tank.

Reference will be had to the accompanying drawings forming a part ofthis specification and wherein like numerals of reference designatecorresponding parts throughout the several views, in which:

. Figure 1 is a plan new of the machine, Fig. 2 is a view in sideelevation thereof, Fig. 3 is a longitudinal sectional view through theentire machine, cut on the line 33 of Fig. 1, and showing in dot anddash lines one of the covers in open position, Fig. 1, is a view inelevation of the driving end of the machine, Fig. 5 is a verticalsectional view out on the line 55 of Fig. 3, Fig. 6 is a detail viewpartly in section, showing the worm-drive and the manner in which theguided crosshead extension straddles the shaft of the worm-gear, andFig. 7 is a sectional detail view of the seals.

The invention comprises a tank or receptacle 1 which contains the dye orother impregnating liquor, and a cage or inner receptacle 2 therein forcontaining the goods to be dyed, washed or otherwise impregnated. Thegoods to be impregnated, ob viously may be of any nature suitable to theprocess, though primarily, the invention is Specification of LettersPatent. Application filed. October 27, 1911. Serial No. 657,083.

designed for the treatment of hosiery and other knit goods. The cage 2comprises imperforate side and end walls 3 and transverse 1mperforatepartitions 5 dividing the cage into a series of substantiallyrectangular compartments, which contain the goods to be treated. Thebottom 6 of each compartment is perforated, being preferably constructedof wire screen. The cover 7 of each compartment likewise is perforated,being also preferably composed of wire screen secured in a rectangularframe 8, and these frames 8 are hinged at 9 to the upper portions of thecage ends 3 and central partitions 5. These door or cover frames 8 reston angle irons 10, secured to the inner walls of the cage and partitionsand forming aledge around each compartment, (see Fig. 5,) and throughthese doors, the goods to be treated are inserted and removed from thecage. When the cage is constructed to be entirely removed from the tank,the perforated bottoms 6 may be likewise secured in similar hingedframes for unloading from the bottom. For locking the covers, bolts 11are provided and these bolts pass through the partitions next adjacentthe cage ends and through the free ends of the covers which are disposedadjacent the said partitions; the covers on opposite sides of thepartitions mentioned last being locked by the same bolts.

The cage is suspended at its ends by means of'hanger-brackets 12, eachof which embraces the adjacent end and side walls of the cage andprojects thereabove. Extending along the upper edge of the end portionof each of said brackets 12, is a reinforcing plate 14 to which isbolted the lateral arms 15 of a cross-head 16. A stub-shaft 17 issocketed into each cross-head and projects therefrom, and to each ofthese projecting portions is attached the upper bearing-box of a pitman18. These pitmen each preferably consists of parallel bars, (see Fig.4,) provided at their opposite ends with adjustable split bearing-boxes19. .The lower bearing-box of each pitman is journaled on a crank orwrist-pin 20 of worm-gear 21,

and each of said worm-gears is journaled on v a stub-shaft 22 projectingfrom each end wall of the tank'l substantially centrally thereof. Onopposite sides of the stubshafts 22, parallel vertical angle bars 24,(see Fig. 6,) are secured to each end wall of the tank, and these formguides for downwardly extending guides 25 of'the crossheads 16, whichguides 25 will beobserved to be cut-out as at 26, (Fig. 6,) to straddleand thereby clear the shaft 22.

Across the ends of the tank 1 extends shafts 27, and 28, one at eachend, these being journaled respectively in bracket bearings 29 and 29'.Each of the shafts 27 and 28 is provided with a housed worm 30 mesh- 7ing with the lower portion of the adjacent worm-gear 21. Motion istransmitted from the shaft 27 to the shaft 28 through a shaft 30journaled longitudinally to the tank in bearings 30". The opposite endsof the shaft 30 are equipped with bevel-gears 31 which mesh with similargears 32, one on the adjacent ends of the shafts 27 and 28 Parallel withthe shaft 27 is a main drive shaft 33 also journaled in the bearingbrack' ets 29 and provided with fast and loose belt pulleys 34 and 35respectively, from one to the other of which the belt (not shown) isshifted by the shifter 36. Motion is imparted from the shaft 33 to theshaft 27 through spur gears 37 and 88 on spective'ly;

Secured means of bolts 40 to the outer faces of'the' walls 3 ofth'e cageand extend ing longitudinally thereof, are substantially U-shape'dfemale packing members in the form of channel-bars 4lof less transversedimension than the space between the walls 1' and 3 of the tank and cagerespectively, (see Figs. 3 and '7.)' Qhannel-bars'42 of correspondingtransverse dimension also constitute substantially U-shap'e'd malepacking members and have their flanges 44 slidingly fitted withintheflange's of' the channel-bars 41, and the outer faces of these bars42 slidingl'y engage the inner'walls of the tank 1. Surrounding theopenings in the bars 41 for the bolts 40', are channelbosse's"46 locatedwithin the channels of the said bars 41, and surrounding these bossesare coil springs'47 bearing at their opposite ends against thechannel-bars 41 and '42 to normally force the same apart; The endchannel-bars 41 and 42, it will be observed, are disposed in differentplanesfroni the planes of the side channel-bars, beingpreferablythereabove. All of the bars extend beyond "the corners of the cagepractically tothe'walls of the tanlnand the'endsof the end-bars 41overlap the ends of the bars running along the's'ides of'the cagefThedye liquor, water,"or other impregnatiiig liquor "is admitted to ordrawn'frofii the said shafts r'e the tankthi ough the pipe the tankbottoin, (see Fig.3.)

"'Ino}5'erat'i ii, hie'fgo'd's or materials are pl ""ed"-vvithifithetemps-menses the was ur; u h the speai gs'ceatrouea by the hingedcovers7, and the covers then secured bythe bolts" 11. Thegoods' arecompactedso as not to move about in the compartments t e ome an-shamed or an e yt 1 enough to insure thorough penetration thereof by the dye or otherimpregnating liquor. Power is then applied to the described gearing toset the same into operation. As the worm-gears 21 rotate, theirWrist-pins 20 operate the pitmen 18 to vertically reciprocate thecross-heads 16 and with them the cage 2. Canting of the cage isprevented by the downward extensions 25 of the cross-heads slidinglyoperating in the guides 24, and as the cross-heads are operated inunison, both ends of the cage 2 are correspondingly raised and loweredin 11mison. The "operation of the cross-heads causes the cage toreciprocate vertically in the tank. This action,'when the cage is movingdownwardly, plunges thegoods into the liquor which has previously beenadmitted into the tank, causing the liquor to pass upwardly through theforaminous cage bottom and through the goods from the under side to theuppermost side of the goods. Vt hen'the cage reaches the bottom of thetank, the action reverses; the cage begi'ns'to rise andlift the goods;This creates 'a'suo tion or partial vacuum on theund'er side of thecage'due was e's'zpansible channel-bars 41'and42 sealing the's'pace' betweenthe tank and cage, and'this suction draws theliquor downwardlythroughthe goods and back into the tank. "Practically all of the liquorcontained in the tank passes through the goods in the cage. The constantmovement of the cage up'an'a down causes the dye or other liquor topass'through the goods in both directions which is believed to be one ofthemostpractical and successful methods of dyeing. The/machine does nothave the fault of roughening or tearing the goods, particularly"the knitgoods. The channel-bars 41 and 42 besides serving thefunctionof seals,serve as cushioning elements 'inthat they absorb anymaterial lateral'vibration of the cage and also serve as automatic centering means forholding the cage at all times centrally of thetank, particularly whenlost motion results'from constant use Having" fully described theinvention, what is desiredto be secured by Letters 'Patcut is:'
